\ Application filed April 10, 1903. SeriaINo. 151,964.

To rzZZ whom, it may concern:

Be it known that we, EDWARD HOLMES, BRITAIN HOLMES, and EDWIN F. BEUGLER, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Machines for Driving Barrel-Hoops, of which the following is a specification.

This invention relates to a machine for driving hoops on barrels or the like.

One of the features of the invention comprises a gear-wheel which transmits power to the hoop-driving mechanism and is held sufficiently against rotation in one direction by a friction device to prevent gravity carrying the hoop-driving mechanism downward and revolves in unison with the friction device in the opposite direction to raise the hoop-driving mechanism. This gear-wheel, together with its friction device, forms a combined power-transmitting and friction locking device.

Another feature has reference to one or more of the driving-arms which are arranged so that they may be moved or swung independently at an angle to the ordinary opening and closing movement of the arms to laterally separate the arms sufiiciently to permit the insertion the hoop-driving mechanism is depressed without elevating the said mechanism.

The main objects of the invention are to construct a comparatively simple, cheap, and eflicient machine of this class that may be operated at a fairly high rate of speed.

The invention also relates to a number of convenient attachments and to minor details of construction, all of which will be fully and clearly hereinafter described and claimed,

reference being had to the accompanying drawings, in which a preferred adaptation of the invention is shown.

In referring to the drawings for the details of the preferred adaptation of the invention like numerals designate like parts.

The frame of the machine consists of a base 1, side frame members 2, bolted to the base by bolts 3, and a top piece or cross-head 4, which is bolted to the upper ends of the side frame members 2 by bolts 5. The top piece or cross-head 4 is provided with rearwardlyextending lugs which are formed to constitute bearings 6, in which a horizontally-extending counter-shaft 7 is journaled, said counter-shaft having a friction device keyed or otherwise fastened upon each end thereof. The friction devices each have a disk 8, provided with depressions 9, in which friction-blocks 10 of wood or other suitable friction material are adjustably mounted, the

blocks-1O being held in position by adjusting-screws 11. (See Figs. 2 and 4.) The bearings 6 are provided with upwardly-eX- tending portions 12, which form bearings for a horizontal sliding shaft 13, to each end of which a hub or sleeve. 14, connected to one part of a collar 15, is fastened. The collar fits in a groove 16 in the hub 17 of a pulley 18, which is loosely mounted near each end of the counter-shaft 7. Each of the pulleys 18 is provided with a beveled part 19, against which the blocks 10 are adapted to be forced .and thus frictionally lock the pulley 18 and the friction-disk 8 together to revolve the counter-shaft 7. The counter-shaft 7 is pro vided with a pinion 20, keyed thereon, which meshes with a gearheel 21, mounted upon a horizontal driven shaft 22, which is rotatably mounted in bearings 23 on the front side of the cross-head 4. The shaft 22 is provided at or near the center of the machine with a pinion 24, meshing with a vertical rackbar 25, upon the lower end of which is mounted the hoop-driving mechanism. This hoop-driving mechanism has a driving head or spider 26, slidably mounted between two vertically-extending guides 26, extendthe side frame members 2,

uide-blocks 27 ,having vertical grooves 28, in which the guides 26 fit- I The driving-head 26 has a central hub 27,

throughwhich the lower end of the rack bar passes, the driVing-head 26 being rigidly fastened thereto by a nut28, which fits 1n a recess or depression 29 in thebottom of the {hub 27 and screws upon the lower screwthreaded end 30 of the rack-bar 25, the nut 30 being locked by a set-screw 31 or other device. (See Figs. 3 and 16.) The drivinghead 26 is also provided with a series of radially-extending portions 32, each of which has a vertical slot 33, in which a vertical driving-arm 34 is pivoted by a pin 35, and each of the driving-arms 34 is provided with a hoop-driving device consisting of a plate 36, having its edges beveled, as at 37 in Figs. 21, 22, and 23, fastened to the enlarged lower end 38 of the driving-arms 34 by a bolt 39, locked in place by a set-screw 40. A guiding device formed of two parts 41, which have a beveled groove in their upper portions corre- .sponding to the beveled sides of the plate 36, over which they fit, is clamped in place by a bolt 42, which passes through openings 43, in both parts and is fastened by a nut 44.

The hoop-driving device is preferably formed as shown in Figs. 16, 20, 21, and 22, the inside edge of the guiding device being curved, as shown at 45, the purpose of which is to guide the driving-arm 34 over the top of the barrel until the projecting portion 46 of the plate 36 grips the hoop and forces it upon the barrel. The hub 27 of the driving-head 26 is provided with an upwardly-extending tubular portion or sleeve 47, and a tubular sleeve 48, rovided near its lower end with a horizontal y-eXtending flange 49, loosely encircles the tubular sleeve 47, with its lower end resting upon the upper part of the hub 27. A series of pins 50 extend vertically above and below the flange 49, and a series of angular-shaped com1ecting-levers 51 are pivoted at their inner ends to the pins 50 and at their outer ends to .the upper ends of the driving-arms 34 by pins 52, which pass through slotted openings 53 in the arms 34. The outer ends of the levers 51 are formed as shown in Fig. 16 and are provided with an elongated depression 54, in which a spiral spring 55 is seated, one end of the spring 55 pression 54 and the other end being held a ainst a flange 56, extending from one end of a pin 57, the flanged end of the pin resting against the inner edge of the driving-arm 34, thus holding the lower end thereof and the hoop-driving devices against the side of the barrel with a spring tension. The drivingarms 34 are spread or drawn together by means of a split collar 58, clampedaround the upper end of the tubular sleeve 48 by a bolt 59 and provided with an operating handle or lever'60, by means of-which the sleeve 48 is partially rotated upon the tubular eX- tension 47 and through the angular levers 51,

contracting or spreading the lower ends of the driving-arms 34, thus providing for different sizes of barrels.

Adevice for preventing the jar of the machine from shifting the lever 60 and moving abutting against the inner wall of the de the driving-arms 34 from their adjusted position is provided, which consists of a collar 61., having an outwardly-extending portion 62, provided with a depression 63 and slot 64, through which a bolt 65 is passed, the bolt being locked in place by upper and lower lock-nuts 66 and 67, the nut 67 being placed in the depression 63. The split collar 58 is also provided with an outwardly-extending portion 68, having a depression 69, in which a spring 70, of curved form, as shown in Figs. 12, 17, and 19, is placed, being held in position by a set-screw 71.

It will be seen from the foregoing description and the drawings that when the handle 60 is moved to bring the highest portion of the spring 70 beneath the lower end of the bolt 65 the collar 58 will be rigidly held against movement by the jar of the machine. The bolt 65 may be moved in the slot 64, so as to provide for the adjustment of the driving-arms to different sizes of barrels.

The collar 61 is rigidly clamped between the upper end of the tubular sleeve 47 and a shoulder 72 on the rack-bar 25. (See Figs. 16 and 1.7.) A heavy coiled spring 72 is placed around the lower end of the rack-bar 25 and upon the upper surface of the collar 61 and acts to relieve the jar when the driving-head reaches its highest elevation by striking against the bottom surface of the cross-head 4. A collar 78 is placed around the upper end of the rack-bar 25 and supports a spiral spring 74, the spring being held in place by a cap 75 and nut 76, screwed upon the upper end of the rack-bar 25. This relieves the jar when the hoopdriving mechanism reaches its lowest posi tion by striking upon the top surface of the cross-head 4.

The upward and downward movement of the hoop-driving mechanism is automatically stopped by means of a bell-crank 73, pivoted upon the rear side of the cross-head 4 and having one end pivoted to one end of a connecting-link 74, the other end of which is pivoted to a downwardly-extending portion 75 on a collar 76, fastened to the sliding shaft 13. The other end of the bell-crank 73'is pivoted to the upper end of a vertically-extending rod 77, which has its lower end pivoted to an operating-lever 78. The vertical rod 77 is provided with upper and lower collars 79 and 80, fastened thereto by setscrews 81 and 82, and two spiral springs 83 and 84 encircle the rod 77, the lower spring 84 being supported upon the collar and the spring 83 resting upon the forked end 85 of an outwardly-extending arm 86, which has its inner end bolted to a lug 87, extending from the driving-head 26. (See Figs. 2 and 15.) The operating-lever 78 is pivoted to one of the side frame members 2 by a bolt 88, and a device for normally holding the lever in a central position is provided, which consists of a short vertical bar 89, having a forked portion fitted upon its upper end, each of the forks 90 having a depression. 91 in its upper end, into which the lower edge of the lever 78 is adapted to fit. A spiral spring 92 encircles the bar 79, with its upper end abutting against the forked portion 90 and its lower end. resting upon a lug 93, extending from the side frame member 2 and into which the lower end of the rod or bar 87 fits andv slides. The forked end 90 straddles the pivoting-point of the lever 78, and thus retains the lever in a central position. A brake device is also provided to prevent the downward movement of the hoop-driving apparatus by gravity and is preferably formed as shown in Figs. 6 and 7, where the details are shown. This brake device has a friction mechanism which is sufficient to hold the hoop-driving mechanism in any position "and against which the hoop-driving mechanism is driven downward by power and a ratchet locking mechanism, which looks the friction mechanism against movement in the direction required to lower the hoop driving mechanism and permits easy movement in the direction necessary to elevate the hoopdriving mechanism. The advantage of this novel construction is that but slight power is necessary to lower the hoop-driving mechanism, as the friction. is just about equal to holding said mechanism stationary, and the ratchet permits the mechanism to be freely elevated, as it relieves the same from the friction. v

The gear-wheel, together with its friction, forms a combined driving and braking device which is operated by power to raise and lower the hoop-driving mechanism and also looks it against downward movement when the power is released.

The gear-wheel 21, mounted upon the shaft 22, has a solid web portion 94, which extends from the rim of the wheel to the hub and forms a depression 95 in one side, in which the brake mechanism is fitted. This mechanism consists of two rings 96 and 97, of wood or other suitable friction material, between which is placed a metal ring or plate 98, having an annular series of ratchet-teeth 99 around its outer portion. Another metal plate 100 is placed upon the friction-ring 97, being held in place by a number of bolts 10]., which pass through openings in the plate 100 and web 94 and are provided at their outer ends with washers 102 and lock-nuts 103. A spiral spring 104 encircles each of the bolts 101, being seated in a depression 105 in the outer face of the web 94, their outer ends abutting against the washers 102. The purpose of the springs is to hold the disks 96 and 97 and metal ring 98 and plate 100 against the inner face of the web 94 with a spring tension. The friction-rings 96 and 97 and metal ring 98 are provided with central openings 106, 107, and 108, through which the bolts 101 pass, so as to permit the rotation of the gearwheel 21 while the friction-rings and ratchet ring or plate are held stationary. A pawl 109 is pivoted to one of the bearings 6 and has one end engaging with the ratchetteeth 99 in the ring 98, being held in engagement therewith by means of a spiral spring Fig. 4.)

of which is to prevent the 110, which encircles a rod 111., one end of the rod being pivoted to the pawl 109 and the opposite end fastened to the cross-head 4. (See The pawl 109 engaging in the teeth 99 of the ring 98 prevents the backward rotation of the ring, and as the ring 98 is held between the disks 96 and 97, which are frictionally locked to the inner face of the web 94 by means of the springs 104, the weight of the hoop-driving apparatus acting upon the pinion 24, shaft 22., and gear-wheel 21 is not sufficient to overcome this friction, and the wheel 21. is held stationary. WVlen, however, power is applied to the pinion 20, the friction between the web 94 and disk 97 is overcome, and thegear-wheel 21 revolves, thus lowering the driving-head 26 and driving the hoop upon the barrel.

An adjustable device is provided for cen tering barrels of different sizes and is preferably formed as follows: A metal plate 112, having a \l-shaped depression, is provided with a groove 113, formed in the upper sur face of one end of the plate, and one edge of the plate is provided with a series of gear teeth 114, with which a gear-wheel 115,

mount ed upon the lower end of an upwardlyextending shaft 116, meshes. The upper end of the shaft 116 is supported by a bearingbar 117, fastened to one of the side frame members 2, and a hand-wheel 118, provided with a series of V-shaped depressions 119, out into the lower surface of the rim thereof, is mounted on the upper end of the shaft 116. The bar 117 is provided with an extension 120, having a depression 121, in which a spring 122 and pin 123 are seated. The pin 123 has its upper end beveled, as shown in Fig. 10. The beveled end of the pin seats in one of the V-shaped depressions 1 19 and pre vents the rotation of the wheel 118 and shaft 116 by the jar of the machine. A strip of metal 124 is fastened to the other side of the extension and has its upper end bent, as shown at 125 in Figs. 1, 3, and 10, the object hand-wheel 118 from disengaging from the pin 123. A plate ,126, provided with a downwardly-extending flange 127 base 1, so groove 113 at its inner end, is bolted to the in the plate 112 and acts as a guide therefor. The plate 126 has a raised portion 128, which acts as a bearing for the lower end of the shaft 116 and alsoas a seat for the gear-wheel 115.

A means for turning the barrel. after the hoops have been driven upon one end is pro that the flange 127 fits in the vided, which is preferably formed as shown in Figs. 1, 2, and 4. Two upwardly-extending and rearwardly-extending portions 129 and 130 are fastened to the base 1 of the ma chine and have their upper ends beveled, as at 131 in Figs. 1 and 2. A horizontally-extending bar 132 rests upon the beveled ends of the portions 129 and 130, being held in place by pins 133, which pass through slots 134 in the bar 132. The pins 133 are seated in the portions 129 and 130 and extend at right angles to the beveled surface 131. Two angular bars 135 extend at approximately right angles to the bar 132 and are pivoted thereto by bolts 132 The forward ends of the bars 135 are bent, as shown, and are provided with cone-shaped pins 136, which are adapted to grip the barrel, and the rear portions of the bars 135 are provided with cylindrical-shaped ends 137, which pass through openings in the lower ends of two levers 138, which extend upwardly and inwardly and are connected at their upper ends to a verticallyextending bar 139 by a pin 140. The bar 139 passes through an opening 141 in the upper end of an angular-shaped bar 142, having its lower end bent and bolted to the base 1,- as shown, and a connecting-lever 143, pivoted at its middle to an extension 143 on the portion 129 has its inner end pivoted to the lower end of the bar 139 and its outer end pivoted to the lower end of a short vertical connectinglink 144, the upper end of which is pivoted to the rear end of a foot-lever 145 by a bolt 146. The foot-lever is pivoted to a fulcrum-bar 147 by a bolt 148 and is provided at its outer end with a foot-treadle 149. The fulcrum-bar 147 is bolted to the base 1 by a bolt 150 and has a slot 151, through which the bolt 148 passes, the pivoting-bolt 148 being locked in place by a lock-nut 152, which is preferably provided with an operating-handle 153, so that the nut 152 may be easily locked or unlocked to provide for the adjustment of the lever 145.

An adjusting-lever 154 for adjusting the height of the bars 135 is provided, which has its rear end bent upon itself, as shown at 155 in Fig. 2, the bent portion forming an opening 156, through which the end of the bar 132 asses. The opening 156 is so formed as to allow a certain range of movement to the bar 132. In order to hold the lever 154 in its adjusted position, a bar 157, having a series of teeth 158 formed upon one side thereof, is bolted to the outside of one of the frame members 2, and the lever 154 is provided with a projecting portion or lug 159, which fits between two of the teeth 158 and holds the lever firmly in position.

A device is provided by means of which the barrel may be removed from the machine before the hoop-driving mechanism has been entirely raised above the barrel, and it is thus bringing and 12. A vertically-extending bar 160 is fastened at its upper end to a bracket 161, bolted to the cross-head 4, anda sleeve 162, having outwardl -eXtending portions 163, is loosely fitted on the bar 160 and adapted to slide thereon. Two levers 164 are pivoted to two of the radially-extending portions 32 by bolts 165, and the inner ends of the levers 164 are loosely seated in depressions 166 in the extensions 163. The outer end of one of the levers 164 is connected to one of the driving arms 34 by a chain 167, and the outer end of the other leyer 164 is connected to another driving-arm 34 by another chain 167 as shown in Fig. 1. Each of these two drivingarms 34 is formed in two parts connected together by a hinge 168 to permit the lower portion of these two arms 34 to swing outward. Weights 169 are bolted to the two hinged arms 34 to normally keep them in a vertical position. The sleeve 162 is provided with two inwardly-extending lugs or ears 170, between which a lever 171, having a cam-shaped end 17 2 is pivoted by a bolt 173. The opposite end of the lever 171 is pivoted to one end of a connecting-link 174, pivotally secured at its other end to acollar 175, mounted on the lever 60, by a bolt 176, which also rigidly fastens the collar 175 around the lever 60. The cam end of the lever 171 passes through an opening 177 in the inner side of the sleeve 162 and operates against a plate 178, which is fitted between the bar 160 and the inner wall of the sleeve.

The operation of the machine is as follows: A barrel is placed in position upon the base of the machine, as Figs. 1, 2, and driven into place upon the barrel is placed around the upper end thereof. is now moved, and by means of the rod 77, bell-crank 73, and connecting-link 74 the shaft 13 is moved to bring one of the pulleys 18 into frictional engagement with its adjacent friction-clutch. This starts the shaft 7 revolving, and by means of the pinion 20 and gear-wheel 21 the shaft 22 is revolved, and the pinion 24, revolving with the shaft 22, carries the rack-bar 25 downward. The lever is now moved to draw the drivers together sufliciently to grip the hoop, and the downward movement of forces the hoop upon the barrel. When the hoop has been driven upon the barrel and the lever 60 is moved to release the drivers from the head and the driving-head has nearly reached its lowest position, the forked end 85 of the arm 86 comes in contact with the spring 84 and carries the rod 77 downward far enough to move the shaft 13 and disengage the pulley 18 from the friction-disk 8. The lever 78 is then moved in an opposite direction and the shaft 13 moved in an opposite direction to the operation first described, into contact the pulley and shown in dotted lines in i 3, and the hoop which is to be The lever 78 the driving-head friction-disk upon the other end of the shaft the link 144 and connecting-lever 143 and spreading the rear ends of the bars 135, thereby embedding the cone-points of the pins 136 in the barrel sides and slightly below the center. After the barrel has been gripped by the pins the continued downward movement of the lever. 145 depresses the rear ends of the bars 135 and raises the barrel from the base of the machine. The barrel being gripped below the center will turn, and the foot-lever being released the bars 135 will lower the barrel upon the base, and the remaining hoops are driven on, as before de scribed. The barrel may be removed from the machine before the drivers have entirely been raised above the top, if desired, and the operation of this mechanism is as follows: After the hoop has been driven upon the barrel, the lever 60 is moved to release the drivers from the hoops, and by meansof the connecting-link 174 the cam end 172 of the lever 171 is brought into contact with the plate 17 8 thus frictionally fastening the sleeve 162 to the bar 160. The upward movement of the driving-head carries the pivoting-points 165 of the levers 164 upwardly, and by means of the chains 167 and 167 a the lower portions of the hinged driving-arms are swung outwardly, permitting the removal of the barrel. When the lever 60 is moved to close the drivers, the cam 172 releases the plate 178, and the drivers resume their normal position. Referring to the means for locking the driving-shaft to the frame to prevent the dropping of the hoop-driving mechanism, the friction-brake is arranged so the frictionrings are held against the gear-wheel with just suiiicient pressure to hold the hoopdriving mechanism from dropping; by gravity, and when power is applied to lower the hoop driving mechanism the gear-wheel rotates against the face of the friction-ring. The advantage of this construction is that it dis-v penses with a heavy weight for counterbalancing the hoop-driving mechanism and forms a combined power transmitting and locking device. The pulleys 18 are belted to a source of power, so as to revolve in opposite directions, so that one pulley is employed to raise the hoop-driving mechanism and the other to lower it.
